Description

Storage device of carbon-sulfur analysis crucible

Technical Field

The invention belongs to the field of chemical experimental equipment, and particularly relates to a storage device of a carbon-sulfur analysis crucible.

Background

The quantitative analysis of the carbon and sulfur contents is one of the important contents for monitoring the quality of steel and metal products. At present, the common analysis method for carbon content and sulfur content in steel and metal materials is a high-frequency induction combustion infrared absorption method, and the working principle of the method is that under the condition of oxygen enrichment, a certain amount of sample and fluxing agent are weighed and placed in a ceramic crucible, a high-frequency electromagnetic field of an instrument is coupled to generate vortex and generate heat, so that the sample is fully combusted, carbon and sulfur in the sample are converted into carbon dioxide and sulfur dioxide, and an infrared pool of the instrument detects characteristic absorption peaks of the carbon dioxide and the sulfur dioxide, so that the carbon content and the sulfur content in the sample are obtained.

In addition, the physical structure of rough micropores on the surface of the crucible leads the crucible to be easy to adsorb carbon dioxide, water vapor and impurity gas containing carbon and sulfur in the environment. If the crucible is directly used for carbon and sulfur analysis, the analysis result of the carbon content and the sulfur content in the sample is higher. Therefore, the crucible for carbon and sulfur analysis must be burned for 4 hours at 1000 ℃ in a muffle furnace, naturally cooled to room temperature, and placed in a glass drying vessel for later use. The drying agent is placed at the bottom of the traditional glass drying vessel, the partition plate is arranged above the drying agent, the crucible to be stored for later use is placed on the partition plate, and the glass cover body is covered by the cover so as to ensure that the environment in the drying vessel is isolated from the outside, thereby achieving the purpose of drying and storing the crucible. When the number of crucibles stored in the glass drying utensil is large, the crucibles are tightly stacked, the drying effect in the utensil is poor, and in addition, the crucibles are taken from the stacked crucibles and are troublesome.
